1 SIMSAM EARLY LIFE Interdisciplinary research on early life exposure and health Coordinator: Anna Rignell-Hydbom Co-coordinator Jonas Björk Division of Occupational and Environmental Medicine, Faculty of Medicine Centre for Economic Demography, Lund University School of Economics and Management Department of Landscape Architecture, Planning and Management, Swedish University of Agricultural Sciences

2 More than 100 publications based on registry, survey and biobank data co-authored by SIMSAM Lund participants. In association to the programme 13 PhD students have defended their thesis. Fourteen new PhD students have started their education within SIMSAM Lund Post-docs have been recruited Several courses, seminars and workshops National and international collaborations SIMSAM Lund

3 SIMSAM Lund – example of articles Associations between gestational complications; gestational diabetes and preeclampsia and air pollution. Malmqvist E, Jakobsson K, Tinnerberg H, Rignell-Hydbom A, Rylander L. Environ Health Perspect. 2013;121: Background A number of studies have shown associations between maternal air pollution exposure and adverse birth outcomes. However; limited information exist for exposure to air pollution and pregnancy complications 81,110 women (singleton births) were linked to individually assessed nitrogen oxides and traffic intensity cases of gestational diabetes, cases of preeclampsia

4 Emission and meteorological National Road database data

6 Maternal smoking during pregnancy and daughters’risk of gestational diabetes and obesity Mattsson K, Källén K, Longnecker MP, Rignell-Hydbom A, Rylander L. Diabetologia 2013;56: Background A study from Norway (the MoBa cohort) showed significant associations However: -Relatively high fraction of non-participants -Smoking data collected retrospectively

7 Study design Inclusion criteria: -Women born 1982 or later who have had at least one child of their own. - Complete data on relevant variables (smoking, BMI, birth weight etc) -Total of women for the final analyses.

9 Cognitive reserve and dementia – Dekhtyar, S., Wang, H-X., Scott, K., Goodman, A., Koupil, I., Herlitz, A. Dementia is a debilitating process characterized by the loss of memory and cognitive function in old age Variations exist in the extent of neuropathology required for dementia diagnoses To explain the disjunction between the extent of brain damage and its clinical manifestation – RESERVE was suggested Brain reserve: anatomical features of brain structure help tolerate more dementia Cognitive reserve: innate intelligence and stimulating life experiences make brain networks more efficient Cognitive reserve is measured by education or occupational complexity Educational and occupational attainment have social and cognitive prerequisites Early cognitive ability could be a better instrument for cognitive reserve A life-course model of cognitive reserve in dementia is yet to be tested
